Abstract
The present invention relates to a droplet jetting apparatus using electrostatic force, a manufacturing method thereof and an ink providing method thereof. The droplet jetting apparatus using electrostatic force includes a lower electrode unit in which a nozzle and a lower electrode positioned in the nozzle equipped in the upper part of a first substrate, and an ink inflow channel equipped in the lower part of the first substrate are integrally formed; an upper electrode unit having an upper electrode formed on the top surface of a second substrate and an ink discharge hole formed by being penetrated to the upper electrode from the bottom surface of the second substrate; and a bonding layer for bonding the lower electrode unit and the upper electrode unit with each other so that the nozzle is vertically aligned with the ink discharge hole. According to this configuration, the ink used in the droplet jetting apparatus is easy to select, the electrostatic force can be efficiently concentrated and manufacturing processes of the droplet jetting apparatus can be simplified.
